Abstract

An image detecting module is disclosed, including a base, a first magnetic element fixed to the base, a slider movably connected to the base, a second magnetic element disposed on the slider, an image detecting unit disposed on the slider, and a coil disposed on the slider or the base. The slider is held in a predetermined position by magnetic attraction between the first and second magnetic elements when no electric current is driven through the coil. When an electric current is driven through the coil, an electromagnetic field is induced by the electric current to eliminate magnetic attraction between the first and second magnetic elements, such that the image detecting unit and the slider are released from the predetermined position and movable with respect to the base.

Claims

exact text as granted — not AI-modified
1 . An image detecting module, comprising:
 a base;   a first magnetic element fixed to the base;   a slider movably connected to the base;   a second magnetic element disposed on the slider;   an image detecting unit disposed on the slider; and   a coil disposed on the slider or the base, wherein when no electric current is driven through the coil, the slider is held in a predetermined position by magnetic attraction between the first and second magnetic elements, and when an electric current is driven through the coil, an electromagnetic field is induced by the electric current to eliminate magnetic attraction between the first and second magnetic elements, such that the image detecting unit and the slider are released from the predetermined position and movable with respect to the base.   
   
   
       2 . The image detecting module as claimed in  claim 1 , wherein the base comprises a rail with the slider sliding thereon. 
   
   
       3 . The image detecting module as claimed in  claim 1 , wherein the slider comprises an annular recess with the coil received therein. 
   
   
       4 . The image detecting module as claimed in  claim 1 , wherein the first magnetic element is a permanent magnet. 
   
   
       5 . The image detecting module as claimed in  claim 1 , wherein the second magnetic element is a permanent magnet. 
   
   
       6 . The image detecting module as claimed in  claim 1 , wherein when the image detecting module is in a focusing mode, the electric current is driven from a power supply to the coil, such that the image detecting unit and the slider are released from the predetermined position and movable with respect to the base. 
   
   
       7 . The image detecting module as claimed in  claim 1 , wherein when the image detecting module is in a photography mode, the electric current is driven from a power supply to the coil, such that the image detecting unit and the slider are released from the predetermined position and movable with respect to the base. 
   
   
       8 . A positioning mechanism, comprising:
 a base;   a first magnetic element fixed to the base;   a slider movably connected to the base;   a second magnetic element disposed on the slider; and   a coil disposed on the slider or the base, wherein when no electric current is driven through the coil, the slider is held in a predetermined position by magnetic attraction between the first and second magnetic elements, and when an electric current is driven through the coil, an electromagnetic field is induced by the electric current to eliminate magnetic attraction between the first and second magnetic elements, such that the slider is released from the predetermined position and movable with respect to the base.   
   
   
       9 . The positioning mechanism as claimed in  claim 8 , wherein the base comprises a rail with the slider sliding thereon. 
   
   
       10 . The positioning mechanism as claimed in  claim 8 , wherein the slider comprises an annular recess with the coil received therein. 
   
   
       11 . The positioning mechanism as claimed in  claim 8 , wherein the first magnetic element is a permanent magnet. 
   
   
       12 . The positioning mechanism as claimed in  claim 8 , wherein the second magnetic element is a permanent magnet.
